Question

what is white blood cells

Answer 1

White blood cells are an important component of your blood system, which is also made up of red blood cells, platelets, and plasma.

Although your white blood cells account for only about 1% of your blood, their impact is significant. White blood cells, also called leukocytes, are essential for good health and protection against illness and disease.

Think of white blood cells as your immunity cells. In a sense, they are continually at war. They flow through your bloodstream to battle viruses, bacteria, and other foreign invaders that threaten your health. When your body is in distress and a particular area is under attack, white blood cells rush in to help destroy the harmful substance and prevent illness.

White blood cells are made inside the bone marrow and stored in your blood and lymphatic tissues. Because some white blood cells have a short lifespan of one to three days, your bone marrow is constantly making them.

Answer 2

WBCs, also called leukocytes, are an important part of the immune system. These cells help fight infections by attacking bacteria, viruses, and germs that invade the body. White blood cells originate in the bone marrow but circulate throughout the bloodstream.
